62f8f307 - powerpc/64: Remove maple platform

Sun, 13 Oct 2024 10:29:57 +0000

powerpc/64: Remove maple platformThe maple platform was added in 2004 [1], to support the "Maple" 970FXevaluation board.It was later used for IBM JS20/JS21 machines, as well as the Biminimachine, aka "Yellow Dog Powerstation".Sadly all those machines have passed into memory, and there's been noevidence for years that anyone is still using any of them.Remove the platform and related code. It can always be reinstated ifthere's interest.Note that this has no impact on support for 970FX based Power Macs.[1]: https://git.kernel.org/pub/scm/linux/kernel/git/mpe/linux-fullhistory.git/commit/?id=f0d068d65c5e555ffcfbc189de32598f6f00770cSigned-off-by: Michael Ellerman Link: https://patch.msgid.link/20241013102957.548291-1-mpe@ellerman.id.au List of files: /linux-6.15/arch/powerpc/boot/Makefile

b1992c37 - kbuild: use $(src) instead of $(srctree)/$(src) for source directory

Sat, 27 Apr 2024 14:55:02 +0000

kbuild: use $(src) instead of $(srctree)/$(src) for source directoryKbuild conventionally uses $(obj)/ for generated files, and $(src)/ forchecked-in source files. It is merely a convention without any functionaldifference. In fact, $(obj) and $(src) are exactly the same, as definedin scripts/Makefile.build: src := $(obj)When the kernel is built in a separate output directory, $(src) doesnot accurately reflect the source directory location. While Kbuildresolves this discrepancy by specifying VPATH=$(srctree) to search forsource files, it does not cover all cases. For example, when adding aheader search path for local headers, -I$(srctree)/$(src) is typicallypassed to the compiler.This introduces inconsistency between upstream and downstream Makefilesbecause $(src) is used instead of $(srctree)/$(src) for the latter.To address this inconsistency, this commit changes the semantics of$(src) so that it always points to the directory in the source tree.Going forward, the variables used in Makefiles will have the followingmeanings: $(obj) - directory in the object tree $(src) - directory in the source tree (changed by this commit) $(objtree) - the top of the kernel object tree $(srctree) - the top of the kernel source treeConsequently, $(srctree)/$(src) in upstream Makefiles need to be replacedwith $(src).Signed-off-by: Masahiro Yamada Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/powerpc/boot/Makefile

b751ed04 - powerpc: drop MPC85xx_CDS platform support

Tue, 20 Jun 2023 04:33:00 +0000

powerpc: drop MPC85xx_CDS platform supportThe MPC8541/8548/8555 Configurable Development System (CDS) were thevehicle used to provide evaluation of the 1st e500-v2 CPUs around 2007.Similar to the earlier MPC83xx-MDS systems we removed, the "brains"exist on a PCI-X card, but additional connectors exist to the right ofthe PCI-X slot, two structural metal pins are used to provide stabilityin a vertical ATX mounting, and the CPU is now on a daughter-card vs. aclamped down BGA.Given the extra complexity and risk of connector damage, the 8548CDSI had access to came pre-assembled in a basic white Antec case commonfor that era, and I'm inclined to assume that was the default.Power was typical "Pentium4" 2005 ATX - the main 20 pin connector wentto the PCI ATX form factor backplane, and the 4 pin black/yellow wentto the CPU card.Like previous evaluation boards, they attempted to provide break-outconnectors for as many features as possible, and that made for a fairlycomplex looking system.In any case, these are over 15 years old, and fairly complex systems,originally made for a small group of industry related people, and madefor use where quiet fan operation wasn't important. Given that, itmakes sense to remove support from them in 2023.Signed-off-by: Paul Gortmaker Signed-off-by: Michael Ellerman Link: https://msgid.link/20230620043300.197546-3-paul.gortmaker@windriver.com List of files: /linux-6.15/arch/powerpc/boot/Makefile

powerpc: drop MPC8540_ADS and MPC8560_ADS platform supportBased on the revision history in the manual(s), these e500-v1platforms were first available around 2002.Like a lot of evaluation boards, they attempted to provide break-outconnectors for all possible features, and that combined with fourPCI-X slots (and the age/era) meant for a considerably large board.As I recall it, from a Linux point of view, the biggest differencebetween 8540 and 8560 was in the UART implementation, and that isreflected in a diff of the defconfigs.In any case, these are over 20 years old, and by today's standardsonly have a small amount of DDR1 memory, and were not widely available.Given that, it makes sense to remove support from them in 2023.Signed-off-by: Paul Gortmaker Signed-off-by: Michael Ellerman Link: https://msgid.link/20230620043300.197546-2-paul.gortmaker@windriver.com List of files: /linux-6.15/arch/powerpc/boot/Makefile
